Rock Mechanics Study of Shaft Stability and Pillar Mining, Homestake Mine, Lead, SD (in Three Parts) - 2) Mine Measurements and Confirmation of Premin
A U.S. Bureau of Mines case study of pillar recovery in high-grade ore near the Ross shaft at the Homestake Mine, Lead, South Dakota, has demonstrated the usefulness of the finite-element method for evaluating shaft pillar mining plans and shaft stability. This report focuses on mine measurements and calibration of the two- dimensional computer model and is the second in a series of three reports of investigations describing the Ross shaft study. In this study, borehole extensometers and other instruments..
